Hardest class you've ever had...

<p>Math 1a, single variable calculus, first term frosh year. Don’t laugh, it was actually incredibly difficult. I’ve taken math through PDE’s and Ma 1a is still the hardest class I’ve ever taken. Luckily, everyone gets to take it on pass/fail at my school. It’s joked that it’s specifically designed to destroy the math major in all of us, and it does convince a lot of would-be math majors to choose a new major.</p>

<p>On grades, ACM 95a, complex analysis (slightly less difficult than Ma 1a). The prof tends to put problems on the exams that he gave to his grad students for their quals. </p>

<p>I will take transport phenomena (heat, mass, momentum transfer in a full year course) this year, which is supposed to be the hardest course that I will take as an undergrad.</p>

<p>Just think about those of us that had to take ACM 95a/100a without having taken a math class in four years. :(</p>

<p>QM is mindblowing. I still don’t have a clear, reliable intuition of what’s going on. I think I’m not alone, given the multitude of interpretations (Copenhagen, GRW collapse, many worlds, Bohmian mechanics, many minds, etc.). Do you know why things are described in a Hilbert space with operators, other than the fact that it works? I don’t.</p>
